Emeralds, like all colored gemstones, are graded using four basic parameters – the four Cs of Gemstones: Color, Cut, Clarity and Crystal. The last C, crystal is a synonym that begins with C for transparency or what gemologists call diaphaneity. Before the 20th century, jewelers used the term water as in a gem of the finest water to express the combination of two qualities, color and crystal. Normally, in the grading of colored gemstones, color is by far the most important criterion. However, in the grading of emerald, crystal considered a close second. Both are necessary conditions. A fine emerald must possess not only a pure verdant green hue as described below, but also a high degree of transparency considered a top gem. In the 1960s, the American jewelry industry changed the definition of emerald to include the green vanadium-bearing beryl as emerald. As a result, vanadium emeralds purchased as emeralds in the United States recognized as such in the UK and Europe. In America, the distinction between traditional emeralds and the new vanadium kind reflected in the use of terms such as Colombian Emerald. Scientifically speaking, color divided into three components: hue, saturation and tone. Yellow and blue, the hues found adjacent to green on the spectral color wheel, are the normal secondary hues found in emerald. Emeralds occur in hues ranging from yellow-green to blue-green. The primary hue must be green. Only gems that are medium to dark in tone considered emerald. Light-toned gems known by the species name, green beryl. In addition, the hue must be bright (vivid). Gray is the normal saturation modifier or mask found in emerald. A grayish green hue is a dull green. Emerald tends to have numerous inclusions and surface breaking fissures. Emerald graded by eye. Thus, if an emerald has no visible inclusions to the eye it considered flawless. Stones that lack surface breaking fissures are extremely rare and therefore almost all emeralds are treated, oiled, to enhance the apparent clarity. Eye-clean stones of a vivid primary green hue with no more than 15% of any secondary hue or combination of a medium-dark tone command the highest prices.6 This relative crystal non-uniformity makes emeralds more likely than other gemstones to be cut into cabochons, rather than faceted shapes.

Poker Ante

An ante is a forced bet in which all players put an equal amount of money or chips into the pot before the deal begins. Often this is either a single unit a one-value or the smallest value in play or some other small amount; a proportion such as a half or a quarter of the minimum bet is also common. An ante paid by every player ensures that a player who folds every round will lose money though slowly, thus providing all players with an incentive, however small; to play the hand rather than toss it in when the opening bet reaches them.

Antes are the most common forced bet in draw poker and stud poker but are uncommon in games featuring blind bets see next section. However, some tournament formats of games featuring blinds impose an ante to discourage extremely tight play. Antes encourage players to play more loosely by lowering the cost of staying in the hand calling relative to the current pot size, offering better pot odds. With antes, more players stay in the hand, which increases pot size and makes for more interesting play. This is considered important to ensure good ratings for televised tournament final. Most televised high stakes cash games also use both blinds and antes. Televised cash games usually have one of the players pay for everyone, normally the dealer, to accelerate play. If there are six players for example, the dealer would toss six times the ante into the pot, paying for each person.

In live cash games where the acting dealer changes each turn, it is not uncommon for the players to agree that the dealer or some other position relative to the button provides the ante for each player. This simplifies betting, but causes minor inequities if other players come and go or miss their turn to deal. During such times, the player can be given a special button indicating the need to pay an ante to the pot known as "posting"; see below upon their return. Some card rooms eliminate these inequities by always dealing all players into every hand whether they are present or not. In such cases casino staff or neighboring players under staff supervision will be expected to post antes and fold hands on behalf of absent players as necessary.
